I applied the updates from sl-testing then rebooted - or tried to but the machine only got as far as starting NIS (at least that was the last message on the screen). It wasn't completely frozen - I could switch between the boot messages and the SL6 circular "counting" logo but couldn't get any sort of access to the machine. I booted SL6.2 from a Live DVD, removed xorg-x11-server packages, yum downgraded the other packages from 6.3 and rebooted successfully. After reupdating these packages in a few batches, rebooting each time I ended up with all the updates and a working system. (The batches were: 1 busybox 2 sos 3 libreport* 4 everything else - by accident). This is the only machine I've tried so far. It uses the "intel" X11 driver on an Intel Corporation 82G965 Integrated Graphics Controller. -- Dr. Andrew C.
